Hey guys, Iâ€™ve been putting off this job for a while, but I finally put a top box on my bike. Instead of using a rack, Iâ€™ve bolted it onto a spare pillion seat. This way I can switch back to the normal pillion seat and there is no hint that I ever had that ugly top box on there. Pics are below, it looks fairly neat and I like the idea of keeping the extra weight where the bike was designed to take it. My only concern is the longevity of the pillion seat; it seems to flex a fair bit out on the road in the wind. But I havenâ€™t tested it with any weight in it yet, I reckon a little weight might make it sit better. Iâ€™ve fitted the Rjays 39L top box. For the money itâ€™s alright, fairly rough, but perfect for my use. I would be quite disappointed if I had to keep using the detachment mechanism for separating the box from the mounting plate. It is an absolute pig to get apart. But being 39L it can fit a massive amount of stuff. My leather jacket, helmet and gloves can be crammed in with a minimum of fuss. What do ya think? Any suggestions about how to reinforce the pillion seat?
